A process is provided for removing contaminants from olefin containing Cstreams. The streams are contacted with an X based zeolite adsorbent comprising greater than 88% X zeolite at a SiO/AlOratio of less than 2.5 and an alkali metal salt present in excess of an amount required to achieve full exchange of cation sites on the X based zeolite. The resulting alkali oxide on a volatile free basis is less than 1% (by mass) of the X based adsorbent. The contaminants that are removed include sulfur, oxygenate, and nitrogen based contaminants.
